Simple ready to go worksheet with accompanying PowerPoint- originally used in Year 6. Provides pupils with the opportunity to practise calculating the area of compound shapes. The PowerPoint is really simple with just the same questions as the sheet, but it allows you to display on the interactive whiteboard for the purpose of whole class marking, supporting groups and modelling and discussing strategies.

A simple PowerPoint with addition and subtraction calculation questions that provide pupils with the opportunity to practise their written methods. For the first activity the 10 questions get progressively harder and I used this as an assessment to identify gaps and group pupils accordingly for teaching input. I repeated these questions at the end of the unit to assess progress and next steps. The second activity includes 13 questions that are grouped in three categories of difficulty. There are two further reasoning activities to consolidate the learning.

Using the context of a dodgy car dealer, children must practise finding fractions of quantities to make sure that they get the best deal. Originally I used this with Year 4, but I think it could also work with Year 5 and less able Year 6 pupils. Resource is provided in PDF and editable Word format.

A lesson originally designed for Y6 class. Resource includes: Powerpoint presentation with activities on place value of decimals and ordering decimals. Fun task cards where children have to use the knowledge they have gained in the context of a supermarket. Printable ‘Star Employee’ stars! (I laminated these and added a safety pin to make it into a badge). For a really wow lesson, you could use the cards as a starting point, but set up the activities using real-life objects (good for an observation!).

This is a great investigation that builds so many rich mathematics connections. It is easily differentiated as the entry point is simple but more able pupils can extend right into algebra. I did this lesson with my Year 6 class, but it could be accessed by pupils across Key Stage 2. It supports the CPA approach to teaching maths as pupils realise that physically moving the ‘people’ (or rubbers, pencil sharpeners or whatever!) across the river (concrete) or using marks on paper (pictorial) really helps with this investigation. Whereas the higher ability pupils can move into the more abstract realm of writing a formula to predict how many trips are needed for x amount of people. Includes lesson plan, a PowerPoint or SMART notebook file so that question can be displayed on the interactive whiteboard and a pupil sheet also with the question on. The lesson also has a starter activity, which is unrelated to the investigation but a nice starter nonetheless!

Supports the CPA approach to teaching mathematics (concrete, pictorial, abstract). Ready to go classroom display aimed at helping pupils to articulate what they have ‘done in their heads’ when adding and subtracting mentally. Encourages pupils to try different strategies and choose the most appropriate strategy for the calculation they are presented with. The resource includes nine thought bubbles with pictorial representations of the strategies and nine text boxes with the strategies in writing, as well as the title. PDF version is included and also fully editable Microsoft Word version (font is Sassoon Primary but can easily be changed). Suitable for use in both KS1 and KS2. This resource can also be bought as part of a package of mental addition and subtraction activities.

This resource has seven multi-step problems to solve. Some of the problems have two examples, so you can work through the first example as a class to develop strategies and then the pupils can have a go independently. Alternatively, let them have a go first and then demonstrate more efficient strategies. There is also a quick starter activity based on measures as this was a focus for my class at the time and some of the questions involve converting measures. The questions are provided in SMART Notebook and PowerPoint format for display on the interactive whiteboard, and in PDF and Word format as a paper resource. These were originally used in Year 4 as an end of term activity and are based on the NNS Puzzles and Problems for Years 3 & 4; however, they could be used across KS2 with different levels of support. Ideas for use: Time filler for stolen moments at the end of term. Developing problem / investigation solving. Stick the question onto a large piece of paper and solve as a group. Adult-led guided group activity/assessment opportunity. Part of a Travel Agent role play corner. Early finishers work Homework activity School work for pupils going on a long holiday during term time (if you dare!) More able or Upper KS2 pupils could devise their own problems in the same format to truly demonstrate their understanding.

Ready-to-go ideas for developing pupils’ ability to add and subtract mentally and to reason about number. These activities link strongly with the CPA (concrete, pictorial, abstract) approach to teaching maths. I created these activities for a research project I was conducting in school as part of my Maths Specialist Teacher qualification. They are all aimed at improving children’s mental addition and subtraction by developing a broad range of strategies and encouraging them to reason about number. We had found that children were entering KS2 with only a handful of (often cumbersome) mental strategies, e.g. partitioning into tens and units, using number bonds to ten only or counting on/back in ones, and weren’t always applying them appropriately. We used the activities with Y3 and Y4 children, but it can be used from Y2 upwards as it links very strongly with the Y2 curriculum. The resource includes differentiated activities with written descriptions and accompanying interactive whiteboard slides and paper resources where applicable. Slides were originally in SMARTboard format and this is perhaps the best software to use if you have it as the slides can be interacted with this way; however, I have also copied the slides over to a PowerPoint presentation for those without SMARTboard software. Also included is a wall display, which shows visual representations of different strategies for mental addition and subtraction. The activities can be adapted for all year groups and abilities and you will find a lot more mileage in this resource once you get started and the impact on the classes studied in terms of both their confidence and ability in mental maths was phenomenal. National Curriculum Links Pupils should partition numbers in different ways (for example, 23 = 20 + 3 and 23 = 10 + 13) to support subtraction. Recall and use addition and subtraction facts to 20 fluently, and derive and use related facts up to 100 Add and subtract numbers using concrete objects, pictorial representations, and mentally, including: a two-digit number and ones; a two-digit number and tens; two two-digit numbers; adding three one-digit numbers. Show that addition of two numbers can be done in any order (commutative) and subtraction of one number from another cannot Recognise and use the inverse relationship between addition and subtraction and use this to check calculations and solve missing number problems. Pupils practise addition and subtraction to 20 to become increasingly fluent in deriving facts such as using 3 + 7 = 10; 10 – 7 = 3 and 7 = 10 – 3 to calculate 30 + 70 = 100; 100 – 70 = 30 and 70 = 100 – 30. They check their calculations, including by adding to check subtraction and adding numbers in a different order to check addition (for example, 5 + 2 + 1 = 1 + 5 + 2 = 1 + 2 + 5). This establishes commutativity and associativity of addition.

I created these ‘Odd One Out’ activities as part of a maths corridor display. It was designed for use by the whole school (Foundation to Y6) and the aim was the develop reasoning and raise the profile of maths in the school. This could also be used alongside my Developing Reasoning Powerpoint as an activity for staff to try during the session. As well as PDF, resource is provided in Word format for easy editing.

This was a PowerPoint presentation and handout that I put together for a staff meeting in my role as subject-leader. It introduces ideas from the Mathematics Specialist Teacher programme and aims to develop mathematical reasoning. It discusses the importance of reasoning, outlines the mathematical skills required to develop reasoning and provides ideas for activities to develop reasoning. The activities can be adapted to suit any age group and any mathematical concept. Many of the activities could also be adapted across the curriculum. They are self-differentiating, with a low entry point and high ceiling and are very quick and easy to set up. The activities are a great option for lesson starters, mental maths activities or time-fillers. The notes under each slide provide an explanation of the activity and some ideas on how it could be adapted. The handout is provided in both PDF and Microsoft Word format.
